A candidate initially faces East. He turns 90° right, then turns 270° left, then turns 180° right. Which direction is he facing at the end?

Step 1: Write the clockwise compass order North → East → South → West. | Step 2: Begin at East. Treat every 90° right as one clockwise step and every 90° left as one anticlockwise step. | Step 3: Apply the commands separately rather than adding their angles without direction: turns 90° right, then turns 270° left, then turns 180° right. | Step 4: The direction after each command is East → South → West → East. | Step 5: A 180° command reverses facing, while a 270° turn equals a 90° turn in the opposite sense. | Step 6: The last entry in the trace is East, so this is the final orientation. | Final Answer: Option A — East.
